Yet another variant. I want to mostly focus on the Skein in this version, as I'm missing any kind of reference point for a giant skein despite 2 years of conceptual work. Making it cave-themed makes the most sense for a variety of reasons.
With some kind of engine in place, I can comb over all my other caverlasting notes to figure out the gameplay.
I think this is the crux of what's been missing in existing Skein designs.
In this system there are primitives that are as variant-developed as possible, linked together into Layouts in as many ways as possible, with as much variation as possible. Layouts can then connect to themselves internally in a variety of ways, as well to other Layouts.
The overall structure should be infinite, so probably a 2d grid or 3d grid of layouts works best.
Content should also ideally be modular in similar ways to get around the "boring content" problem which is where skeins usually fail.
